State leaders in Massachusetts say a proposed tie-up between NextEra Energy and Dominion Energy warrants close attention because it could worsen already steep power bills for residents.
The concern centers on how much sway one company might hold over the region's electricity system. Officials argue that if too much of New England's supply falls under a single owner, consumers could face higher costs and weaker protection against the exercise of market power.
Here's what to know
The Boston Globe reports that Gov. Maura Healey's office wants the Federal Energy Regulatory Commission to closely examine what the proposed NextEra-Dominion merger could mean for customers in New England.
Rebecca Tepper, Governor Maura Healey's energy secretary, said regulators should "heavily scrutinize the impacts this merger may have on ratepayer bills, market power, and reliability."
Massachusetts's Department of Public Utilities, the attorney general's office, and the New England States Committee on Electricity have each sought a role in the federal case, the Globe reported. Sen. Ed Markey asked FERC to stop the deal, citing affordability and antitrust concerns.
The proposed deal matters especially in New England because these companies own the area's only two remaining nuclear plants: Dominion's Millstone in Waterford, Connecticut, and NextEra's Seabrook in New Hampshire.

Those facilities produce roughly one-fourth of the region's electricity. Approval of the merger would put both plants under NextEra, leaving a single out-of-state company with substantial influence over a key slice of the regional grid.
The dispute is unfolding as New England has grown more receptive to nuclear power, which provides steady electricity without the carbon emissions associated with fossil fuels. That renewed interest makes Millstone and Seabrook more important and strengthens the bargaining position of whoever owns them.
Doubts about NextEra are also tied to its past campaign against a transmission line through Maine that would have delivered Canadian hydropower. The resulting delays pushed that project's price to $1.6 billion, more than 50% above the original estimate, and Massachusetts ratepayers ended up bearing those extra costs.
What's being done?
The immediate battle is at FERC, which can approve the merger, deny it, or impose conditions. Massachusetts regulators cannot make the final decision because neither company owns a local utility, but they are trying to press their case in the proceeding.
Who controls large generating stations can affect contract talks, wholesale power prices, and long-term reliability choices, all of which can eventually influence what households pay for electricity.
At the same time, state officials are considering wider policy issues such as whether Massachusetts ought to ease its long-standing limits on new nuclear development. The discussion underscores how central dependable, affordable, low-emissions electricity has become in New England.
Residents have few alternatives when wholesale electricity costs climb. That is why state officials say close regulatory review matters here: a corporate deal negotiated outside the region could still directly affect family budgets.
